提出了基于轮廓形状分析的图素识别方法，该方法克服了轮廓矢量匹配识别算法的缺陷（在图素生成或曲线跟踪过程中，在分枝点出现的生长或跟踪错误），提高了图素识别的完整性．轮廓形状分析还被用于字符串与图线粘连下的字符串提取 A new method based on contour shape analysis is proposed, which overcomes the defects of contour vector matching recognition algorithm (growth or tracking error at branch point during the process of pixel generation or curve tracking) Recognition of the integrity. Contour shape analysis is also used for character string and graph line under the string extraction
